Abstract: This design is a Gao Bazhou 3 stand-alone capacity of 84 mw of small hydroelectric

power station. The raw data of the first according to the given task according to the book, analyze and determine the design scheme of power plants. Respectively from the power supply reliability, flexibility, advancement of technology, analyzing various kinds of the feasible solutions to the main electrical wiring, and determined the optimal solution. Then according to the identified the main electrical wiring and power supply range determines the main transformer sets, capacity and its model, but also determine the capacity of the factory with the transformer and its model. According to the working point of the continuous working current and short-circuit current calculation results, the high voltage circuit breaker, isolating switch, bus, voltage transformer, current transformer, insulator and wear casing wall, lightning and other electrical equipment selection and calibration. After through CAD software to draw the main electrical wiring diagram of hydropower station and distribution equipment arrangement plan.

Keywords: the main electrical wiring, short-circuit calculation, electrical equipment, power
